Parameter Comparison

Engineering Selection Recommendations

The LB16SKW01-5C12-JC is the direct substitute for the obsolete LB16SKW01-12-JC. Both components maintain identical electrical specifications, current and voltage ratings, mechanical dimensions, and lifecycle performance. The substitute part holds active product status with current manufacturing availability, ensuring long-term supply chain reliability.

The primary technical difference is the illumination technology: the substitute employs LED illumination powered by 12VDC instead of incandescent illumination powered by 12VAC. This change requires verification of the illumination power supply in the target application. LED illumination offers extended operational life and reduced power consumption compared to incandescent technology.

Both parts maintain ROHS3 compliance and identical moisture sensitivity levels, supporting equivalent environmental and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can LB16SKW01-5C12-JC directly replace LB16SKW01-12-JC in existing designs?

A: Electrical and mechanical compatibility is complete. The illumination power supply must be evaluated: the original part requires 12VAC, while the substitute requires 12VDC. If the application provides 12VAC illumination power, a power supply modification is necessary.

Q: Are the panel cutout dimensions identical?

A: Yes. Both parts require a square panel cutout of 16.20mm x 16.20mm, enabling direct mechanical interchange without panel modification.

Q: What is the difference in illumination technology?

A: LB16SKW01-12-JC uses incandescent red illumination, while LB16SKW01-5C12-JC uses LED red illumination. LED technology provides longer operational life and lower power consumption.

Q: Are the electrical ratings identical?

A: Yes. Both parts are rated for 3A at 125V AC and 30V DC with SPDT on-on switching function and identical electrical life of 100,000 cycles.

Q: What is the product status difference?

A: LB16SKW01-12-JC is obsolete with no current manufacturing. LB16SKW01-5C12-JC is active with current production and inventory availability.

Q: Are termination styles compatible?

A: Yes. Both parts use identical termination: Solder and Quick Connect - 0.110" (2.8mm), enabling direct connection compatibility.
